Voltage Gain of a Tube

Author: E.E. Kimberly

The amplification factor μ of a tube cannot be considered as all profit because only the change of voltage across the load resistance RL is available for use. The voltage gain vg must be calculated by comparing the change in voltage across RL only with change in ec. The voltage change across RL is only proportional to the total change in ep because the circuit contains
